1. Day 11
The Last Week!

2. Review Data types: Java supplied: Color, String, int, double, boolean
Programmer created: Day, Rectangle, Car, Picture

3. Review: Object Oriented Programming
Instantiate objects: (example) Car mazda = new Car(25);
Methods: use the dot operator on an object to call a method
Signature: Public (sometimes private), return type, name, parameter in parenthesis:
public void drive(double distance)
Accessors: int currentYear=day1.getYear();
Mutators: rectangle1.translate(5,10); (Note: the return type is void)
Constructors: No return type & requires new operator, see example above

4. Review--Variables
Parameters: Passed into methods and are in the parentheses.
Instance variable: private, at the top of a class
Local variables: used in a method to make a calculation. Declare once by stating type
Scope

5. Review--Design
Pseudocode helps to create algorithms: calculation, repetition, decision
Designing classes:
Documentation helps to read others’ classes
Create a plan for the methods, their signatures (1st lines) and the instance variables
Test the classes directly through BlueJ or write a TesterClass with a main method

6. Review Loops
Initialize, increment & test
While loop
For loop

7. Review--decisions if, if – else, if - else if - else
Relational operators
Logical operators
